Commit c1dc7b6b27d4d1c0b45b8f287aa0dc8e90414e77 removed a function which
added the ability to sort a marker selection table.

Fixes https://jira.thehyve.nl/browse/UAT-184

inclusion.

UAT-183 Added better color palletes for two analyses

LineGraph and Scatterplot used the default palette, which does not
contain easily distinguishable colors. Palletes with higher contrasts
have been added.
Allow single/no group variable in Line Graph

Fixes UAT-177 and UAT-176 (respectively).

ColumnConfigurators: add header as common property
Fix extra data LineGraph

and possibly other analysis that used OptionalBinningColumnConfigurator
with keyForIsCategorical set. Problem was that setting the
MissingValueAction to a constant value to account for the case when no
variable is selected (see UAT-176) is too strong an action. If the
selected variable doesn't have data for some patients, those patients
would nevertheless show up (under SINGLE_GROUP).

Resolved this with an OptionalColumnConfiguratorDecorator, which is
anywat what I wanted to all along. This decorator delegates to two
different sub-configurators, selected based on whether some param key is
set.

Fixes UAT-177 (likely among other problems), previously broken by the
fix for UAT-176.
